Cannot get armature to move the mesh
See this answer regarding mirroring bones.
The armature has to be a &quot;parent&quot; of the mesh in order to move it. In order to do this, in Object Mode select the mesh then Shift + click the armature. Ctrl + P to parent and select With Automatic Weights for best results. You can move the bones by selecting the armature and switching to pose mode.
I suggest watching/reading a comprehensive guide for rigging a character and adjusting it, as it's challenging, even for intermediate users.
